Once upon a time, people had this device working with smartthings, but they were using the parent/child paradigm that worked with the classic app and does not work with the current V3 app. 
Which probably means the entire thing has to be written to match the new platform.
If you’d like to talk to some of the people who had it working before, see the following thread:
GE Zwave Dual Control Dimmer 28175
Note that this device has two different model numbers, which is typical for the ones built by Jasco. It is Jasco ZW3106, but GE 28175. You may need to search under both model numbers.
